glXQueryContextInfoEXT()                 glXQueryContextInfoEXT()


NAME    [Toc]    [Back]

       glXQueryContextInfoEXT - query context information

SYNOPSIS    [Toc]    [Back]

       int glXQueryContextInfoEXT(
               Display *dpy,
               GLXContext ctx,
               int attribute,
               int *value );

PARAMETERS    [Toc]    [Back]

       Specifies the connection to the X server.  Specifies a GLX
       rendering context.  The visual ID  that  the  context  was
       created  with.   The  X screen the the context was created
       for.  The context with which this context  shares  display
       lists.  or  NULL  if  this  context does not share display
       lists.

DESCRIPTION    [Toc]    [Back]

       glXQueryContextInfoEXT() returns the the visual id, screen
       number, and share list of ctx. This call may cause a round
       trip to the server.

       glXQueryContextInfoEXT() is part of the EXT_import_context
       extension,  not  part  of  the  core  GLX command set.  If
       GLX_EXT_import_context is included in the string  returned
       by  glXQueryExtensionsString(),  when called with argument
       GLX_EXTENSIONS, extension EXT_import_context is supported.

ERRORS    [Toc]    [Back]

       GLXBadContext  is  generated  if  ctx  does not refer to a
       valid context.
